devot:eeDevoted to ExpressionEngine

Hi everyone,
I have the following problem, this morning I was trying to put a huge list of emails to put in the “banned list” of my Expression Engine, and after give to update button I was taken out of the control panel, and I was not able to login again. My website isn’t working, and I have not been able to find a solution. I would like to know if somebody here can help me to fix the problem. I would appreciate so much, since I am in a big trouble. Thank you in advance.
